UNDEBFBAHE.

Specification of Letters Patent.

Patented June 16, 1914.

1'o all whom it may concern:

Be it known that I CLAUB J. WERNER CLASEN, a citizen of the United States of America, and resident of Davenport, Scott county, Iowa, have invented a .certam new and useful Improvement in Underframes, of which the followin is a specification.

My invention re ates to the underframes of railway cars and especially to that type of underframes in which the center sill ex tends continuously from end to end of the car, and is directed more particularly to the improved formation and application of the draft arms and body bolsters to the center sill.

The main object of my invention is provide means of attaching the draft rigging to a continuously extended center sill in a manner that will leave free and unobstructed the upper portion of the web and all of the up per edge or flange of the center s ll by any part or portion of the draft rigging 1n the vicinity of its connection thereto.

Another object of the invention is to provide a strong and substantial union of the center sill and draft arms where intersected by the body bolster.

These and other objects which will hereinafter appear, are attained by the structure illustrated in the accompanying drawings, in which Figure 1. is a side elevation, partly in section, of the side of a car at one end, provided with av single I beam center sill and showing my improved draft arms in place. Fi .2. is a vertical cross section of a portion 0 a car taken n line C-D of Fig. 1. Fig. 3. is a plan view of the end of the single I beam center sill, shOWili" in dotted lines the mannor of applying the draft arms and bolster thereto. Fig. 4. is a vertical cross section of the center sill and draft arms taken on line AB of Fig. 3.

Similar numerals refer to similar parts throughout the several views.

While a fragmentarv view of one end only of the car is shown, it is to be understood that the other end is a duplicate of the end shown and that the center sill 1, preferably an I beam. extends continuously from end sill 2 to a similar end sill at the other end. The lower flange of this I beam center sill and a portion of the web are coped off or cut away. for some distance back from each end as indicated by the dotted line E. F. G. in F1g. 1, formin a recess or indent. Located in the pocket t us formed are the draft arms 3-3, one on each side of the center sill web, forming a housing or supporting structure for the draft ear mechanism and through which the bufllng shocks and pulling strains are transmitted to the center sill. These draft arms are riveted to the web of the center sill along its severed edge through the medium of the vertical flanges 3 made into a1 therewith. From the lower edge of trees flanges 3 the walls of the draft arms, for the eater portion of their length, extend latera ly for a short distance and thence downwardly, thus forming a passage way for the upper limb of the draw-bar yoke. These walls again extend laterally for another short distance and thence downwardly, terminating in the outwardly projecting flanges 3", thus formin the housing pro or for the reception of t e draft gear mec iamsm.

At the rear end the walls of the draft arms are bent or brought in toward and closely embrace the web of the center sill and extend on a distance past the point of intersection of the body bolster 4 and the center sill. The flanges 3 lap over and are riveted to the lower flange of the center sill. Registering with and following the contour of the H shaped opening in the center sill through which body bolster 4 passes, are the flanges 3 extending a distance laterally from the draft arms and made integral therewith. These laterally extending flanges or gussets closely embrace all surfaces of the body bolster where in contact with it and are usually riveted to the vertical web of the bolster. The forward end 3 of the draft arms extend beyond the end sill 2 to receive the striking plate 5. In the lower part of the outer end the draw-bar carry iron 6 is fitted and held in position by bolt 7. The outer end of the vertical flange 3 is increased in height and terminates in the laterally extending flange 3 by which it is secured to the end sill 2.

It is to be understood that the laterally extending flanges or gussets 3 could be made separable from and riveted to the outer face of the draft arms 3;, and these draft arms could be cast integral without departing from the spirit of my invention.

What I claim as new is' 1. In an underframe for cars end sills, a center sill extending from end sill to end s ll,

body bolsters, and draft arms the rear ends of which closely embrace the center sill and extend body b0 sters.

2. In an underframe for cars, end sills, a center sill. extending from endsill to endsill, and draft arms closely embracing and secured to the said center sill. in the intersecting planes of the body bolsters.

3, In an underframe for cars, end sills, a single I beam center sill extendin from end sill to end sill, and cast metal raft arms closely embracing and secured to the said ee'nter'sill in the intersecting planes of the body bolsters.

4. In an underframe for cars, a center sill proyided with longitudinal indents at each end, draft arms occupying said indents, and the rear ends of which extend ast the intersecting planes of the body b0 sters.

5. In an underframe for'cars, a center sill provided with longitudinal indents at each end, draft arms occupying said indents and lapping the web of the center sill past the intersecting planes of the body bolsters.

6. In an underframe for cars, center sills provided with longitudinal indents at each end, draft arms occupying said indents, the rear ends of which extend ast the intersectini planes of the body bo sters, said center sil and draft arms having openings in their lap ed, portions for the passage of the said b0 y be sters.

7. In an underframe for cars, center sills provided, with longitudinal indents at each end, draft arms occupying said indents and lapping the web of said center sills ast the intersecting )lanes of the body olsters, said center si ls and draft arms having parts of their lapping ortions dis laced to permit the passage oi said body holsters.

8. In an underframe for cars, a flanged beam center sill having recesses formed by removing the lower flange and a portion of its vertical web for a distance back from each end, draft arms occupying said recesses and secured to and lapping the web of said center sill past the intersecting planes of the body bolsters.

i). In an underframe for cars, a flanged beam center sill having recesses formed by removing the lower flan e and a ortion of its vertical web, for a distance ack from each end draft arms occupying said recesscs an secured to and lappln the web of said center sill past the intersecting plane of the body bolster, and having openings in m oving the lower flange and a ast the intersecting planes of thetheir lapped portions for the throu h 'Of'SlIld' body bolster.
